SEWAGE-DISPOSAL PLANT.

Specification of Letters Patent. A

Patented May 28,1912.

Application led March 12, 1912. Serial No. 683,398.

To all whom t may concern.'

Be it known that I, ALBERT H. Tm-IR, a citizen of'the United States, residing at Mount lVashington, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Sewage-DisposalPlants, of which the following is a specification.

This invention relates to improvements in sewage disposal plants.

The invention consists of the novel construction and arrangement of the part-s and combination of parts hereinafter more` fully set forth in the following specification and pointed `out in detail in the claims.

In the accompanying drawings,-Figure 1 is a vertical sectional view ,of our invention. Fig. 2'is a vertical sectional view on 4side wall of the tank and is provided with the line X-X of Fig. 1. Fig.A 8 is a plan view of our invention,l partly broken away.

Referring to the accompanying drawings, forming part of this specification and in which like reference numeralsdesignate like parts through the several views thereof, 1, 2, 3 and 4 designate Yintercommunicating tanks. The tank l is provided with a sewage inlet pipe 5 at one side o f the central wall and a sewage outlet pipe 6 at the other side of said wall. These tanks are all provided with bottom's sloping downwardly from yeach side thereof toward the center, andVv with bathe or partition walls 7 terminating below the top of the tanks. The central wall 8 extends the full length of all of said tanks and projects downwardly from the top and terminates in a flared lower end 9 above the bottom of the tanks and is partly cut away in the tank 4 to allow the sewage to flow around said wall to the other side of the tank 4 and back through the tanks on the opposite side of the central wall to the outlet.. The walls 10, 10 extend the full length of said tanks and project downwardly from the top on a vert-ical line to o r about the top of the partition walls 7 at which point they converge and terminate above the flared end 9V of the central wall 8. The tanks 1, 2, 3 and 4 are each provided with a pipe 11 which projects from near the bottom of the tank up through the a valve 12 on the outside, by means of which the flow of the sludge from the tanks is regulated. The tanks are each provided with man holes 13 to permit of entrance thereto at the different points thereof. The

tanks are also provided with reinforced beams 14 to brace the tops of the tanks and also to act as baiie walls. The outlet 6 is surrounded on the inside by a set-off or projection 16 the upper end of which is open and above the lower ends of the walls 14. The sewage enters the tank 1 on one side of the central wall 8 through the pipe 5 and as it rises in said tank the sludge rises and falls, and in so doing strikes against the converging ends of the wall l0, and the flared end of the wall 8, which act as baffles to prevent the sludge flowing into the tank `2 with -the water, which latter flows up between the central wall 8 and the wall 10 on that side and overflows .into the tank 2. The same action takes place in tank 2 as that just described in tank 1, andan'y sludge which may pass into tank 2 will sink to the bottom thereof. The water ows from tank 2 to tank 3 and then to tank 4, the flared end of the wall 8 and the converging end of the wall 10 acting as baffles in each tank to prevent thesludgel passing therefrom with the-water. By the time the water reaches tank 4 it is practically clear and Hows there-from back into tank 3, then to tank 2 and finally to tank 1, on the opposite side of the wall 8, and out through the out-let pipe 6 to the aseptic bed (not shown) whereit receives its final purification. The flow of the sewage being down one side of the centralwall 8 and back on the opposite side and out through the outlet 6. The projection or off-set 16 being above the lower ends of thewalls 14 the latter also serve as baies against which any solid matter may strike and fall in the tank below. In the lower end of the tank 1 is a pipe 17 by means of which connection can be made for the purpose of flushingsaid tanks and cleaning same. The partitlon walls 7 are also provided with apertures 15 at the lower end.4 The sludge which remains in the tanks 1, 2, 3 and 4 is siphoned off through the pipes 11, and carried to any desired point.

While we have shown and described our invention as embodying four tanks, it- 'is obvious any number of tanks may be employed.

Having thus described my invention, what I claim is:

1. A plurality of intercommunicating tanks, the first one of which has an inletand outlet, a central wall extending the full length of all of said tanks and projecting from the top to near the bottom thereof and partly out away in the last tank, and two walls extendin the full len h of all of said tanks an projecting om the top thereof and converging toward the central wall and terminating above the lower end i of the latter.

tanks, a central wall extending the full 2. A plurality of intercommnnicating tanks `.lt-hiewtirst oneof which has an inlet andz=an..ontlet, a central wall extending the full lengthv of all of said tanks and projecting from the top terminating in a flared lower end vabove the bottoms of said tanks, and partly cut away in the last tank, and two walls extending the full length of all of said tanks and projecting from the to thereof and converging toward and terminating above the flared lower end of the central wall. l

3. A plurality of intercommunicating tanks having an inlet and an outletpthe partition walls 0f said' `tanks terminating below the top thereof, a central wall extending the full length of all ofsaid tanks and projecting from the top downwardly and terminating in a flared end above the bottoms of said tanks and partly/,cut away in the last tank, two walls extending thefull length of all of said tanks and projecting downwardly on a straight line to the to of the partition walls of said tanks an then converging toward and terminating above the flared end of the central wall.

4. A plurality of intercommunicating tanks having the bottoms thereof sloping from each side toward the middle, and the partition walls of said tanks `terminating below the top of the tanks, an inlet pipe connected to one of said tanks, an outlet pipe Iconnected to the same lone of said length of all of said tanks and projecting from the top downwardly and terminating in a flared end above the bottom of said tanks, and partly cut away in the last tank, two walls extending the full length of all of said ltanks and projecting downwardly full length of all of' said tanks and projecting downwardly on a straight line to the top of the partition walls of said tanks and then converging toward and terminating above the flared end of the central wall, and a pipe extending from near the bottom of each tank upwardlyjhrough the side wall near the top thereo t 6. A plurality of intercommunicating tanks having their bottoms sloping downwardly from each side thereof toward the center and the partition walls of said tanks, terminating below the top thereof, an inlet pipe leading to the first tank, an outlet pipe leading from the same tank, a central wall projecting the full length of all of the said tanks and extending downwardly from the top and terminating in a flared end above the bottoms of said tanks, and partly cut .away in the last tank, two walls projecting "the full length of said tanks parallel with the central wall and having their lower ends converging toward and terminating above the flared end of the central wall, a pipe extendingrfrom near the bottom of each tank upwardly and projecting through the side- Wall near the top thereof, and a valve in each of said pipes.

, yIn testimony whereof I aiiix my signature inp'resence of two witnesses.
